- Ref ring now to the drawings,-in Fig. 1 the1"-.- s shown a blank 11 for the forniation of the inner member. This blank is slit at 12, 12 at about the line between the heel and the shank. The blank is properly tempered and while in this soft and pliable condition, is subjected to pressure andheat between suitable dies, the center let of the blank and the others of To all whom it may concern:

Be it known that'I, EUGENE H. TAYLOR, a citizen of the UnitedStates, residing at Boston, county of Sufi'olk, State of Massachusetts, have invented a certain new and in Processes of Making Insoles, of which the following is a specification, reference being had therein to the accompanying drawings.

In United States Letters Patent to George Coleman No. 1,062,536, dated May 20,1913, there is shown a composite insole composed of" two layers of split or other thin leather. feather 13. The blank is submitted to the This insole is found to have many practical pressure and heat between the dies for a advantages and the material from which it length of time sufficient to give the parts a is made is very cheap, but attempts which permanent set or shape. The inner member have been made to produce these insoles resulting from steps described so far is commercially by machine have failed. The shown in Fig. 2. machines for making these insoles have In Fig. 4 there is formed the edges progressively beginning which the outer member of the insole is near the toe or heel and following around the edge. It has been found that satisfactory. insoles cannot be produced by this method at a reasonable cost. Y

My invention, therefore, has for its object a new and improved method of making substantially the insole shown in said Coleman patent, which shall obviate the objections previously referred to. Accordingly, in practising my invention I form at one time the entire folded edge of each of the members which together compose the insole, and then assemble and unite the two members.

My invention will be fully understood from the following description taken in connection with the accompanying drawings and the novel features thereof will be ointed out and clearly defined in the claims at the close of the specification.

In the drawings,Figure 1 shows the and is then subjected to pressure and heat between dies, one of which occupies the center 16 of the blank and is of a slightly smaller size than the area of the blank as determined by the outer periphery of the finished member. The other dies bend the margin of the blank over the edge of the inner die and turn it up to form a lip 17. The dies are then withdrawn leaving the blank in the shape shown in Figs. 5 and 6 with an edge portion 18 bent back upon itself fromthe edge of the insole and an upwardly projecting lip or feather 17. The time, pressure, and heat to which the two blanks are subjected are all regulated as will be understood by art of handling leather and the leather is given the desired permanent set and stifi'- ness, its shape being determined by the shape of the dies. Thereafter, the inner member 11 is assembled within the edge of the outer member 15 and the two are preferably secured togetherby adhesive spread over their adjacent surfaces. The parts are again subjected to pressure and heat after being as" sembled so that they The herein described method may be best and most economically practised by having three machines all of the same general character one of which forms the inner, and another of which forms the outer member composing the finished insole and the third of which squeezes together the assembled parts.

insole is produced. Fig. 2 is a view in perspective of said inner member in its finished form. Fig. 3 is a section on line 3-3 of Fig. 2.. Fig. 4 is a plan view of a blank from which the outer member is formed. Fig. 5 is a view in perspective of the said outer blank. Fig. 6 is a section on line 6 6 of Fig. 5. Fig. 7 is a view in perspec- 'tive of the completed insole composed by superposing the inner member shown in Fig. 2 on the outer member shown in Fig. 5, said two members being in proper reiamade. This blank is also properly tempered those skilled in the.

one of which occupies which turn up its margin to form a lip or shown a blank 15 from are then firmly united.

If amber maybe rapidly and almost instantly shaped and the membcrs are always perfect replicas of each other and do not vary in size or in any of their dimensio s What I claim is:

1. The method of making a composite insole which comprises tempering a piece of stock, forming an upwardly projecting rib about a portion of its periphery, the whole of said rib being formed at the same time by subjecting the blank to pressure and heat between dies, withdrawing the dies, insertng within the shaped piece an inner piece having an upwardly turned edge adapted to lie in contact with said rib, and subjecting both pieces to pressure to cause them to adhere.

2. The method of making a composite insole which comprises tempering a piece of stock, forming an upwardly projecting rib about a portion of its periphery, the whole of said rib being formed at the same time by subjecting the blank to pressure and heat between dies, withdrawing the dies, inserting within the shaped piece an inner piece having an upwardly turned edge adapted to lie in contact with said rib, and subjecting both pieces to pressure and heat to cause them to adhere.

In testimony whereof I afiix my signature, in presence of two witnesses.
